WINDMILL.

SPECIFICATION forming part 0f Letters Patent NO. 431,983, dated July 8, 1890. Application filed April 3, 1890. Serial No. 346,390. (No model.)

To all whom, it may concern:

Be it known that I, OSCAR J. KILBY, a citizen of the United States, residing at Lancaster, in the county of Grant and St-ate of Wisconsin, have invented certain new and useful Improvements in Windmills; and I do hereby declare that the following is a full, clear, and exact description of the same, reference beinghad to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

This invention relates to certain new and useful improvements in windmills, and it has for its object, among others, to provide a device ot' this character which shall be simple,

cheap, and durable; and the novelty resides in the peculiar combinations and the construction, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawings, and then particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure 1 is a side elevation of myimproved wheel. Fig. 2 is an edge view of the same. Fig. 3 is a detail in vertical section showing the screw-shaft. Fig. 4 is a face view of one of the gear-Wheels. Fig. 5 is a top plan showing the gear-wheels and their relation to the pinion on the screw-shaft.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates the tower, preferably formed of gas-pipe or other tubular material, and'near its top provided with a surrounding brace A and at the top with a cap A2. Through this cap and through a suitable guide-tube a near the brace A passes the rotatable tube B, which serves as the turn-table on which the mill turns. Upon the upper end of this tube there is asleeve B', which is secured thereto in any suitable manner, and formed with an arm Z), which extends up and over the top of the tube, as shown in Fig. 3, the horizontal portion thereof being provided with an opening for the reception of the sleeve D, which is internally screw threaded, as shown in Fig. 3, and carries apinion C, which is confined between the arm Z1 and the upper end of the guide-tube B.

E is the screw-shaft, which is threaded' to engage the threads of the sleeve D, and below the threaded portion is hollow, as shown in Fig. 3, and designed to be connected with the pump-rod.

Journaled in a suitable bearing c on the tube B is a horizontal shaft CZ, which carries two gear-wheels F, oppositely arranged, as shown in Fig. 5, and each of these wheels is toothed for a half of its circumference only, the two wheels being so arranged that the toothed portion of one is opposite the plain portion of the other, as shown. These wheels mesh alternately with the pinion C on the sleeve D, and as the wheel is turned by the wind they cause the screw-shaft, and colisequently the pump-rod, to be reciprocated'in first one direction and then the other. As soon as the teeth of one wheel has caused the pinion to revolve for a distance in one direc tion, the teethof that wheel leave the teeth of the pinion and the teeth of the opposite wheel come into mesh with the pinion, and

acting or revolving in the opposite direction give an opposite movement to the pump-rod. On one end of this shaft CZ there is fixed a pulley G, and sleeved on this shaft is the bifurcated arm e, which at its lower end carries a weight H, as seen best in Fig. l, and sleeved on this same shaft, but extending to the opposite side thereof, yet in one piece with or so connected with the Weighted arm as to be moved therewith, is the brace or arm I, in the lower end of which is journaled the horizontal shaft J, on which the wheel is supported. I2 is a bent brace-arm attached to the arm I and sleeved on the shaft CZ as a brace. On the hub of the wheel K there is aiiixeda pnlley I', over which and over the pulley Gr passes the endless band or chain L.

M is a cord or chain'having one end attached to the weighted arm e, and the other end, after passing through a suitable hole f in the tube B and a vertical slot g in the hollow portion of the screw-rod, extends to Within convenient reach from the ground. The pulley on the wheel shaft or hub is smaller than that of the shaft d, for the purpose of gearing the same down, so as to prevent too fast reciprocation of the pump-rod, as owing to the small wheel employed the vast number of revolutions per minute would tend to reciprocate the pumprod too fast.

Vhen it is desired to throw the wheel out of the wind,it is only necessary to pull upon the cord M, when the parts will assume the position in which they are shown in full lines in Fig. 1, the effect of which is to give the wheel a leverage upon the wheel-frame, so that by the wind it will be turned with its edge thereto. Vhen the wheel is in the wind, the Weighted arm serves to regulate the same.

Instead of wheels or pulleys, as shown i-n Fig. 2, I may sometimes employ sprocketwheels and a sprocket-chain, as shownin Fig. l.

What I claim as new is- 1. The combination, with the tower and the guide-tube, of the screw-shaft and the pumprod connected thereto, the screw -threaded sleeve thereon, the pinion carried by said sleeve, the horizontal shaft, and the gearwheels thereon, each wheel having a toothed portion and an untoothed portion, the toothed portion of one arranged opposite the untoothed portion of the other and engaging directly with said pinion, substantially as and for the purpose specified.

2. The combination, with the tower and the guide-tube and thewind-wheel, of the screwthreaded sleeve at the upper end of the tube,

the screw-shaft engaging the threads of the sleeve and connected to the pump-rod, the pinion on said sleeve, the horizontal shaft supported on the sleeve, and the gear-Wheels on the shaft, having toothed and untoothed portions, the toothed portion of one being arranged opposite the untoothed portion of the other and the two arranged to alternately engagedirectly with and revolve the pinion in opposite directions, and thereby reciprocate the pump-rod, as set forth.

3. The combi-nation, with the tower and the guide-tube and the wind-wheel, of the armi? on the tube, the sleeve within the upper end of the tube, the pinion on the sleeve between the arm b and the upper end of the tube, the sleeve being internally threaded, the screwshaft engaging the threads of the sleeve and connected to the pump-rod, the transverse shaft supported on the tube, and the gearwheels on said shaft and arranged upon opposite sides of the pinion, each wheel having a. toothed and an untoothed portion, said toothed and untoothed portions being oppositely arranged and alternately engaging directly the said pinion, as and for the purpose specified.

4. The combination, with the guide-tube, the pump-rod, .the screw-shaft connected to said rod, and the transverse shaft supported thereby, of the swinging arm on the shaft, the wheel carried by the outer end of said arm, the screw-shaft-operating devices, and a chain and suitable pulleys connecting the wheel-shaft therewith, as set forth.

5. The combination, with the guide-tube and the transverse shaft supported thereby, of the swinging arm on the shaft and carrying the wheel, the swinging weighted arm also on said shaft, the screw-shaft and the pump-rod connected thereto, the gears andl pinions for operating the same, and the endless chain connecting the shafts of the wheel and gears, substantially as and for the purpose specified.

In testimony that I claim the above l have hereunto subscribed my name in the presence of two witnesses.

OSCAR J. KILBY.
